EDWARD SWAINSON, OF LIVINGSTON, MONTANA.

NAIL-EXTRACTOR.

To all whom it may concern.

Be it known that I, EDWARD SwArNsoN, a citizen of the United States, residing at Livingston, in the county of Park and State of Montana, have invented new and useful Improvements in Nail-Extractors, of which the following is a specification.

The present invention provides a tool primarily intended for removing nails, but which may be easily adapted for use in the capacity of a wrench for turning nuts or pipe.

r1`he invention supplies a tool which will enable nails to be extracted without bending the same so that the nails may be used again without requiring straightening thereof before they may be driven. The tool also embodies a hammer poll whereby nails may be driven and a jaw may be substituted for the nail extracting when the tool is required to be used in the capacity of a wrench.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawing, and pointed out in the appended claims.

Referring to the drawing, forming a part of the application,` Figure 1 is a side view of a tool embodying the invention. Fig. 2 is a sectional view on the line 00-012 of Fig. 1. Fig. 3 is a detail view of an interchangeable jaw.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawing, by the same reference characters.

The tool embodies a handle 1, which is provided at one end with a fixed jaw 2 and a hammer poll 8 and at the opposite end with a grip 4. The handle 1 is crimped in` termediate of its ends, as shown at 5, to provide a depression to receive the shank of the movable jaw. A rounded projection 6 is formed upon one side of the handle 1 near the jaw 2. The several parts may be of integral formation and may be of any construction.

The movable jaw 7 has a shank 8, the jaw and shank being uniformly curved upon the outer edge, whereby the tool may be rocked thereon when used for extracting nails. The jaw 7 has a nib 9 at its outer end corresponding to the nib of the jaw 2, both nibs being pointed so as to readily Specification of Letters Patent.

penetrate the wood about the head of the nail to enable the latter to be firmly gripped preliminary to the drawing operation. rPhe jaw 7 is formed upon its inner side with a rounded depression 10 corresponding to the rounded project-ion 6 upon which it is mounted. rlhe inner or rear end of the shank 8 has an elongated slot 11 through which passes a bolt or fastening 12- by means of which the forked ends of an operating bar 13 are connected to said shank. Two plates 14 embrace opposite sides of the jaw 7 and the rounded projection 6 of the handle I, said plates being of approximately Y- form and having their branch-es bolted or otherwise secured to the jaw 7 by means of fastenings 7a and their stems pivotally connected to the handle 1 by means of a bolt or fastening 15. the latter passing through an opening' of the handle 1 concentric with the curvature of the projection 6. Lateral displacement of the jaw 7 is prevented b v means of the plates 14 and said jaw is caused to rock upon the projection 6 when opening or closing the jaws. l

The operating bar 13 is adapted to have a longitudinal movem-ent imparted thereto and is confined to the handle 1 by means of a keeper 16 and an eye 17, both of which are bolted or otherwise secured to the handle 1. rEhe forward portion of the operating bar 13 is of square form, whereas the rear portion is made rounding to operate through the eye 17 and to receive an 'expansible spring 18 of the helical type, the latter being confined between the eye 17 and the shoulder 19 formed between the square and rounded parts of the operating bar. The rear end of the operating bar is forme-d with a grip 20, which extends tranversely of the tool and is adapted to be gripped by the hand holding the grip 4. The slot 11 formed in the shank 8 of the movable jaw is inclined to the plane of movement of the operating bar 18, hence when the operating bar is pressed forward by the spring 18 the bolt or fastening 12 rides upon the inner wall of the slot 11 and moves the rear end of the shank 8 toward the handle 1, but when the operating bar 18 is drawn outward, as when gripping the parts 4 and 20, .the bolt or fastening 12 rides upon the outer wall of the slot 11 and moves the shank 8 outward at its rear end, thereby causing the jaw 7 to bring the nibs of the jaws together so as to grip the head of the nail received'between them. A keeper 21 applied to the forward end of the operating bar 13 serves to prevent lateral displacement of the shank 8.

The jaw 7a indicated in Fig. 3 is interchangeable with the jaw 7 and is of similar construction thereto with the exception that the gripping end 22 is made straight and inclined and formed with a series of serrations so as to firmly grip the work that may be placed between said aw and the jaw of the handle l when the wrench jaw is substituted for the nail extracting jaw.

lVhen a nail is to be extracted the tool is placed so that the head of the nail comes between the nibs of the jaws 2 and 7 and force is exerted lengthwise upon the handle to cause the nibs of the jaws to bite into the wood so as to obtain a firm grip upon the nail adjacent the head. After the tool has been properly set the grips l and 2O are grasped in the hand, thereby closing the jaws upon the nail, after which the tool is rocked upon the curved edge of the jaw 7, which serves as a fulcrum, thereby resulting in a pulling of the nail in the manner well understood.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while have described the principle of operation of the invention,y together with the device which I now consider to be the embodiment thereof, l desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention what is claimed as new, is:-

1. A tool of the character set forth comprising a handle having a jaw at one end and a rounded projection at one side near the jaw, a movable jaw located at one side of. the handle and having a rounded recess upon its inner side to receive the rounded projection at the side of the handle and having its outer edge made rounding for the tool to rock upon when in active operation, means pivotally connecting the two jaws, and means for turning the movable jaw upon its pivotal connection with the fixed jaw and upon the rounded projection, the tool being adapted to rock upon the rounded edge of the movable jaw and its shank in the plane of movement of said movable jaw.

2. A tool of the character described comprising a handle having a` fixed jaw at one end and a rounded projection at one side near said jaw, a movable aw at one side of the handle having a shank and having a rounded recess upon its inner side to receive the rounded projection and having the outer edge of the jaw and shank made rounding for the tool to rock upon when in active operation, the outer end of the curved shank having a slot, means pivotally connecting the two jaws, an operating bar slidably mounted upon the handle, and means connecting the inner end of the operating bar with the slotted end of the shank of the movable aw.

3. A tool of the character specified comprising a handle having a grip atone end, a fixed jaw at its opposite end and a rounded projection at one side near the jaw, a movable jaw located at one side of the handle and having a curved shank and provided upon its inner side with a rounder recess to receive said rounded projection, plates embracing opposite sides of the jaws and rig idly connected to the movable jaw and pivotally connected to the fixed jaw, an operat ing bar slidably mounted upon the handle and having a grip at its outer' end, and means connecting the inner end of the operating bar with the shank of the movable aw, the parts being arranged whereby upon imparting a sliding movement to the operating bar the jaws are opened or closed.

et. A tool of the character described comprising a handle having a grip at one end and a jaw and rounded projection at the opposite end and crimped intermediate of its ends, a movable jaw having a rounded recess receiving said rounded projection and formed with a shank having an elongated slot, plates embracing opposite sides of the movable jaw and rounded projection and secured to the movable jaw and pivotally connected to the handle concentric with the rounded projection and recess, an operating bar slidably mounted upon the handle and having its forward end forked and embracing opposite sides of the slotted shank, a fastening connecting the forked ends of the operating bar and passing through the slot of the shank of the movable jaw, guide means provided upon the handle for retaining the operating bar in place and directing the same in its reciprocating movements, a grip at the outer or rear end of the operating bar, and a spring mounted upon said operating bar and normally exerting a pressure thereon to hold the jaws open.

1n testimony whereof I affix my signature in presence of two witnesses.
